This article explores the scientific and methodological foundations for developing students’ graphical thinking through the integration of geometry and computer science. The study provides an in-depth analysis of the role of an integrated teaching system in enhancing spatial imagination and its impact on fostering logical and creative thinking competencies through graphical interfaces. Within the research framework, the influence of interactive environments created using the CeDG (Computer Extended Descriptive Geometry) model, AutoCAD, KOMPAS-3D, and Blender on the learning process was empirically examined. Based on statistical analyses, visual graphics, and innovative tabular data, it was demonstrated that presenting geometry in a modernized format significantly enhances students’ potential. Specifically, effective methodologies for developing graphical thinking through 3D modeling in virtual environments, interactive exercises, and project-based assignments are presented. The research findings substantiate the relevance of implementing integrated educational technologies to prepare modern technical specialists by harmoniously combining geometry and computer science.
